A valve 4| is adapted to seat in the upper end of the passage 48 to close the latter. The valve 4| is threadedly connected to one end of a sleeve 42 disposed for reciprocation within the passage 38, and the remaining end of the sleeve 42- is provided with an inwardly directed flange 43 adapted slidably to receive an operating rod 44. A collar member 45 is fixed to the lower end of the operating rod 44 by means of a pin 48 which projects outwardly beyond the periphery of the collar and into diametrically opposite slots 41 provided in the sleeve member 42. 'Ihe collar member 45 makes a sliding fit within the sleeve member 42. A bearing plug 58 is threaded into the upper end of the vertical passage 38 slidably to receive the operating rodv 44. A sylphon bellows 5| is employed to effect a seal between the operating rod 44 and the upper end of the boss portion 31 of the housing member I8. The sylphon bellows 5| is preferably welded at one end to the operating rod 44 as indicated at 52 and at the other end to the top of the boss portion 31 as indicated at 53.

A comparatively heavy spring 54 is 4coiled about the operating rod 44 and interposed in compressed condition between the plug member 50 and the flanged end 43 of the sleeve member 42 normally to urge the sleeve member and the valve 4| downwardly so that the latter seats within the upper end of the passage 40 to close the same. A lighter coil spring 55 is also disposed around the operating rod 44 and arranged in compressed condition between the flange 43 of the sleeve 42 and the collar member 45 so that it normally biases the operating rod 44 in a downward direction to maintain the pin 46 at the lower end of the slot 41. Upward movement of the operating rod 44 serves to overcome the biasing action of the light coil spring 55 causing the pin member 46 to move upwardly within the slot 41 until the pin reaches its upper end. Continued upward movement of the operating rod 44 after the pin 46 has reached the upper end of the slot 41 eifects the elevation of the sleeve member 42 against the biasing action of the heavier coil spring 54 and opens the valve member 4I.

A manual control lever 58 provided with a ball or handle portion 51 is pivoted as indicated at 60 to a bracket member 8| xed to the upper end of the boss portion 31 and is provided at the other end with a slot 62 adapted to cooperate with a pin 54 projecting through the operating rod 44 for elevating the latter. The upper end of the operating rod 44 is connected by a pin and slot connection 65 to one end of a beam member 68 which is provided with a pin 61 at an intermediate point adapted to be received in an open notch 10 at the upper end of an upstanding bracket 1| vilxed to the top cover plate I2 and provided at the second end thereof with a forked portion 12 of saddle-like formation and adapted normally to cooperate with a pin 15 fixed to the upper end of an operating rod 16 for maintaining the latter in elevated position. The operating rod 16 is sealed to the cover plate |2 by means of a sylphon bellows 13 welded as indicated at 14 and 11 to the operating rod and cover plate l2.

'I'he operating rod 18 is provided with a sleeve member 18 at the lower end thereof by which it may be detachably connected by means of a bolt and wing nut assembly 8| to a refrigerant holder disposed within the refrigerant chamber The refrigerant holder 80 is preferably in the form of a basket-like carrier having peras solid carbon dioxide, is arranged within the Vholder 80 and normally rests upon the bottom surface thereof. As the refrigerant 82 evaporates the space between the refrigerant and the side walls of the refrigerant chamber increases. However, the space between the refrigerant and the thin bottom wall 23 remains stationed unless intentionally changed. While the coil spring 55 is made weaker than the coil spring 54, it is of suilicient strength normally to maintain the basket or holder 88 in elevated position and maintain the refrigerant spaced from the thin bottom wall 23.

A conduit 84 leads from the top of the refrigerant chamber into the outlet passage 33 of the liquid containe'i 3| so that the liquid therein may be carbonated, if desired. A throttle valve 85 is interposed within the conduit for regulating the amount of carbonation of the liquid within the container 3| or for shutting oil.' the passage of carbon dioxide from the refrigerant chamber to the passage 33. A throttle valve 88 is also provided in the passage 40 for adjustablyrestricting this passage so that the charac-` ter of the foam produced upon a carbonated beverage may be controlled as desired.

In the operation of the device, a liquid to be dispensed and cooled is admitted through the inlet 32 into the liquid container 3| and may be cooled to a certain extent by heat transferred therefrom by means of the fins 24, the heat being absorbed in vaporizing the solid carbon dioxide 82 supported within the holder 80. When it is desired to dispense the liquid from the container 3| the cooling of the same may be intensifled by actuating the ma'nual control lever 51 in a clockwise direction viewed in Figure 1 to elevate the operating rod 44 against the tension of the coil spring 55 thus causing counter clockwise rotation of the beam member 68 and lowering of the refrigerant holder 80 until the refrigerant 82 is brought into close proximity to the thin heat conducting wall 23 of the refrigerant chamber With the refrigerant 82 disposed closely adjacent the thin heat conducting wall 23, heat will rapidly be extracted from the liquid contained within the chamber 3| and the heat absorbed by the refrigerant 82. The fins 24 afford extensive surface area in contact with the liquid during the absorption of heat therefrom. After the manual operating lever 58 has been depressed to a position, such as indicated for example at 81, in which the refrigerant holder is lowered to a position adjacent the heat conducting wall 23, but before the valve 4| has been opened, and the actuating lever maintained in this position for a few seconds, it may be then depressed to a further position, indicated at 88, which effects the elevation of the sleeve 42 within the passage 38 and opens the valve 4| permitting a cooled or refrigerated liquid to be dispensed from the device.
